Question

What is the inverse of the function f(x) = 2x + 1? h(x) = one-halfx – one-half h(x) = one-halfx + one-half h(x) = one-halfx – 2 h(x) = one-halfx + 2

Answer 1

x = 2f(x) + 1

2f(x) = x - 1

h(x) = 1/2x - 1/2

Explanation:

Answer 2

Explanation:

To find the inverse we just switch f(x) and x so we get :

x = 2f(x) + 1

2f(x) = x - 1

h(x) = 1/2x - 1/2

Hope this helps!
